Let f be a one one function with domain = { x , y , z } and range = { 1 , 2 , 3 } . It is given that exactly one of the following statements is true and the remaining two are false : f ( x ) = 1 , f ( y )  = 1 , f ( z )  = 2 , then f − 1 ( 1 ) = ____

TestHub · Accepted Answer

f ( x ) = 1 ( F ) ⇒ f ( x ) = 2 or 3 ​ f ( y )  = 1 ( F ) ⇒ f ( y ) = 1 ​ f ( z )  = 2 ( T ) ⇒ f ( z ) = 1 or 3 ​
